Figure 1

Schematic representation of identified EULarchitectures found in Embryophyta. Some putative EUL proteins comprise one EUL domain, while others comprise two in tandem arrayed EUL domains. In most EUL proteins the EUL domain is preceded by an unrelated N-terminal domain varying in length. In a few EUL proteins a signal peptide was detected at the N-terminus. Some EUL proteins comprise a C-terminal domain which can also differ in length. In two-domain EUL proteins the two domains are separated by a linker.
